Application filed. December 12, 1914. Serial No. 876,905.

To all whom it may concern Be it known that I, ALEXANDER LEKsUozIN, acitizen of the United States, residing at Detroit, in the county ofWVayne and State of Michigan, have invented certain new and usefulImprovements in Permutation-Locks, of which the following is aspecification.

This invention relates to certain new and useful improvements inpermutation looks.

The primary object of the invention is to provide a permutation lockparticularly adapted for use in connection with a bicycle or likevehicle and having permutation locking means engageable for preventingmovemember.

ment of the propelling means of such vehicle.

A further object of the device is to provide a locking bolt engageablewith a member for preventing the operation of such member, such boltbeing controlled by a permutation lock mounted adjacent the 'With thesegeneral objects in view and others that will appear as the nature of theinvention is better understood, the same consists in the novelcombination and arrangement of parts to be hereinafter more fullydescribed, illustrated in the accompanying drawings and set forth in theappended claims.

In the drawings forming a part of this application and in whichlike-designating characters refer to corresponding parts throughout theseveral views, Figure 1 is a side elevation of a bicycle frame providedwith the present device and partially shown in section. Fig. 2 is anenlarged side view of the permutation lock in position to be actuatedfor releasing the bolt. Fig. 3 is a side view of the same with thepermutation rings removed and taken at an angle of 90 degrees from thepoint of view shown in.

Fig. 2. Fig. 4 is a view similar to Fig. 2 but with the permutationrings and cap removed. Fig. 5 is a transverse sectional view taken uponline V-V of Fig. 9. Fig. 6 is a transverse sectional view taken uponline VIVI of Fig. 8. Fig. 7 is a perspective view of the guard plate.Fig. 8 is a central longitudinal sectional view through the lock withportions of the bicycle frame, the lock bolt being broken away and theelements positioned as found when'the device is locked. Fig. 9 is asimilar view partly in elevation with the elements in their unlockedposition. Fig. 10 is a perspective view of one of the locking tumblers.Fig. 11 is a similar view of the other tumbler. Fig. 12 is a perspectiveview of a portion of the locking bolt. Flg. 13 is a perspective view ofa portion of one of the permutation rings showing the tumbler releasingmeans, and Fig. 14 is a perspective of the upper portion of theremovable side of the lock casing.

Referring more in detail to the drawings a bicycle frame 10 is hereinillustrated having the present invention installed'upon the centraltubular brace or frame member 11 The look is provided with a tubularcasing 12 having tapered ends 13 in which are screw-threaded union caps1a which caps are provided with sockets 15 adapted for the reception ofthe adjacent portions of the frame tubing 11 in which manner the casingforms a part of the frame member 11, the said caps 14E being alsosecured to the tubing ends by rivets 16.

The crank shaft 17 of the bicycle extends through the sleeve 18 and isprovided with a sprocket wheel 19 in the usual manner but also has atoothed wheel 20 centrally positioned thereon and in direct alinementwith the longitudinal axis of the frame tube 11 and is adapted to beengaged by a sliding bolt 21 in the form of a rod which is positionedthrough the tubing 11, the lock casing and the caps 11, being slidablyjournaled in the said casing and caps. coil spring 22 encircles the bolt21 and normally holds the same in its unlocked retracted position.

The casing 12 is provided with a removable side 23 which formssubstantially onehalf of the tubular casing wall whereby thelock-mechanism is positioned within the easing whilesaid removable sideis secured in position by means of a rivet 47 and the ring cap 47hereinafter described.

A guard plate 25 is secured longitudinally within the chamber 26 of thecasing by means of rivets 27, and is provided with notches 28 upon itsopposite side and adjacent its ends for the sliding reception of theprojecting lugs 29 carried by the tumblers 30 which are of substantiallyidentical form and one of which is best illustrated in Fig. 10. The bolt21 has a flattened portion 31 spaced from its upper end and the tumblersare adapted to ride over the said flattened portion while the boltslides through the cut-away portion 32 of the tumblers, the flattenedportion of the bolt being adapted bolt portion when the bolt isretracted in its.

unlocked position. Similar leaf springs 36 are carried by lugs 37 uponthe opposite sides of the. flattened portions 31 and said springs engagethe faces 38 of the bases 39 V of the tumblers. The tumblers are eachprovided with'a projection 40 upon. its base which is adapted to projectthrough slots 41 in the casing. wall while a forcing of said tumblers iseffected. for releasing the bolt by means of, pressure exerted upontheouter end of the said extensions 40 and through the agency ofreleasing means carriedby the permutation rings in a manner hereinafterS t for A releasing latch 42is movably positioned transversely of thecasing having one end reduced as at 43 and loosely pivoted in a recess44 at one side of; the casing while the opposite end of the latchextends through a longitudinal slot 45 in the opposite side of: thecasing and also through. a similar slot 46 in a permutation. cap 47,which,cap is mounted upon the'upper end of; the casing and is retainedthereon by means of the V rivet 47 and asi nilar rivet 24 passingthrough the casing 12. The latch 42 isprovided with a terminal knob 48exteriorly of the casing end, and the latch being freely ex tendedthrough atransverse perforation 49 of the bolt 21, itwillbe seen thatwhen the tumblers are released from their engagement; with the bolt, adownward movement of the knob 48 will lower the bolt to itslocked,position against the normal action of the spring 22 which will beextended and placed under tension. A transverse pi-n- 50 is carried bythe latch 42 interiorly of the casing, which preventsthe latch frombeing removed therefrom.

Two outer and two inner permutation rings. 51 and- 52 respectively arejournaled for turning uponythe exterior cylindrical surface of thecasing and between-the ring cap 47 and theannular ring 53 of the casing.The ring cap .47 and the ring 43 as well as each of the journaled ringsare provided with any desiredarrangement ofnumbers as 54. for providingcombination numbersby which the lock may be operated.

' The inner rings 52 perform no function in the boltreleasingoperationbut are for the purpose of acting asablind to confuse unauthorizedpersons, from attempting to operate the permutation look by means of. acombination of the numbers disclosed thereon. Each of the outer rings 51is pro-. vided with a longitudinal socket 55 on its inner face in whicha leaf spring 56 is positioned' being secured to the ring at one end 5-7thereof and; provided with a push pin 58 at its other end which projectsthrough an opening 59 in the ring whereby the spring 56 may be pushedinwardly to engage theouter end of the adjacent tumbler extension 40when the carrying ring is accurately positioned with the pin end of thespring directly thereover as illustrated in Figs. 5 and 9.

vVhen the bolt is'projected in its locked position as illustrated inFig. 8, the tumblers are engaged in the deeper notches 34 of the boltand prevent a longitudinal movement thereof, while the extensions 40 liewithin the openings 41 and have their outer faces substantially flushwith the outer periphery of the casing while the outerrrings 51 areadapted to be turned directly over the ends of said extensions. Whendesired to'release the bolt by retracting the same, the outer rings 51are turned tothe required position which in the present manner ofarrangement as illustrated in Fig. 2 consists of p0 sitioning thepushpins 58 in direct alinement between the upper number 7 and the lowernumber 9. When so positioned, the pins 58 may be bothpressed inwardlythus moving the tumblers inwardly and releasing them from engagementwith the notches of. the bolt which allowsthe spring 22 to retract thebolt and hold the same out of engagement with the teeth of the toothedwheel 20. The rings52 and 51 may be then we turned to any positiondesired and the lock is adapted to be again placed in its lockingposition by a downwardimovement upon the latch knob 48, the springs 36forcing the projecting lug 29 into engagement with the 105 deepernotches 34 of the bolt when the bolt is in its locked position as shownin Fig. 8.

The complete operation of the device will thus be apparent, it beingseen that when the toothed wheel 20 is prevented from turning 110 by alocking of the bolt, the bicycle cannot beoperated, but when the bolt isreleased all obstruction to the operation thereof is removed.

Vhile the form of the invention herein 115 shown and described is whatis believed to be the preferred embodiments thereof, it is tumblers anda projecting latch pivoted within the said casing and engaging said boltand extending through said casing slot.
